Definitions

  • the invention relates to freely pivotable trailing wheels according to the preamble of claim 1.
  • Such trailing wheels are known for example from EP-PS 0332835 ( Figures 3 and 4). They are used to allow the work machine to move kinematically and freely behind the towing tractor when cornering. Their disadvantage, however, is that the pivot axis for the trailing wheels significantly exceeds the wheel diameter in height, so that only wheels of relatively small diameter can be accommodated in the installation space available under the rotating work tool. To compensate for this disadvantage, it has already been proposed to use double wheels as trailing wheels, such as. B. shown in DE-PS 40 13 789.
  • the invention aims to avoid the described disadvantage simply, functionally and inexpensively.
  • trailing wheels are proposed, the material pivot axes of which do not project beyond the outer diameter of the trailing wheels. It is particularly advantageous if the material pivot axes do not project beyond the outer diameter of the wheel rims at any point. This can be achieved particularly advantageously in that the pivot axes are inclined to the wheel plane, and that the imaginary extension of the pivot axis pierces the ground approximately in the central plane of the trailing wheels and in the direction of travel before the contact point of the trailing wheels.
  • two trailing wheels are arranged on a two-armed pendulum axis in the direction of travel at a distance from one another such that the inclinations of the pivot axes of both trailing wheels, as seen in the direction of travel, are mirror images of one another.
  • a rotary hay machine with a machine frame (1) is pivotably connected to a mounting frame (3) about a vertical pivot axis (2), which in turn is connected to a tractor (not shown) is grown.
  • a work gyroscope (4) is mounted on the machine frame (1) so that it can be driven and rotated about a vertical axis (5).
  • Axle supports (6) are firmly connected to the machine frame (1).
  • Wheel arms (7) are mounted so that they can move in height on the axle supports (6).
  • Two-arm pendulum axles (8) are mounted on these wheel rockers (7) so that they can pivot about a horizontal axis of rotation (9).
  • the two-armed pendulum axles (8) each have at their free ends an axis fist (10), the central axis (11) of which is inclined from behind such that it is spread downwards (FIGS. 3 to 5).
  • a pin (12) penetrates the bore of the axis fist (10). This is enclosed by a bearing sleeve (13).
  • the bearing sleeve (13) is fixedly connected to a wheel axle (15) by means of a web (14).
  • An impeller (16) with a rim (17) is rotatably mounted on the wheel axle (15).
  • the central axis (11) When viewed from the side, the central axis (11) is also inclined such that, viewed in the direction of travel, it hits the ground at a distance a in front of the wheel center (FIG. 4).
  • the spreading angle ⁇ is chosen (FIG. 3) such that the central axis (11), which is also the pivot axis for the trailing wheel (16), pierces the ground in the central plane of the impeller (16).
  • the axis fist (10 ') is inclined only in a vertical plane lying transversely to the direction of travel with a spreading angle ⁇ ' to the impeller plane.
  • the axle fist (10 ') is penetrated by a double cranked wheel axle (18), on the horizontal axle journal of which an impeller (16) with a rim (17) is rotatably mounted. With this arrangement there is a caster offset b.
  • a front trailing wheel (16) is arranged on the inside and a rear trailing wheel (16) on the outside (FIG. 2). Since both trailing wheels are in the Swing in the same direction, because of the mirror-image spread of the swivel axes (11), the swivel axis of one wheel is raised and that of the other wheel is lowered. The result is that the height of the axis of rotation (9) remains approximately unchanged and thus also the distance of the working tools from the ground.
